摘要
以CuSO4·5H2 O ,Na2 MoO4·2H2 O ,phen ,H3 PO4为原料,用中温水热合成技术制得了一种新型一维链状配合物[Cu(phen) (H2 O) 2 ]SO4,并通过元素分析,红外线和X射线单晶衍射法进行了结构表征。晶体属于单斜晶系,空间群为C2 /c ,a =1.4 85 3(3)nm ,b =1.3811(3)nm ,c =0 .70 10 (14 )nm ,β=10 8.6 5 0°,V =1.36 2 5 (15 )nm3 ,Dc =1.832g/cm3 ,R1=0 .0 2 90 ,wR2 =0 .0 86 2 ,F(0 0 0 ) =76 4 ,Z =4。X射线单晶衍射和IR光谱结果表明,在固态条件下配阳离子与SO42 -之间存在氢键作用,Cu2 + 与2个氮原子和2个氧原子配位。另外还进行了热性质研究。
The title complex [Cu(C12H8N2) · (H2O)2]SO4 was synthesized by hydrothermal method and characterized by elemental analysis, IR and X-ray single crystal structural analysis. The crystal structure indicates that the compound forms a stratiform, built from the SO42- and [Cu(C12H8N2) · (H2O)2]2+ through hydrogen bonds. The chemical formula weight of complex is 375.84. The crystal structure is monoclinic, pace group C2/c with a = 1.485 3(3) nm, b = 1.381 1(3) nm, c = 0.701 0(14) nm, β = 108.650°, V= 1.362 5(15) nm3, Dc = 1.832 g/cm3 ,F(000) = 764, Z = 4,R1 = 0.0290, wR2 = 0.0862. The result of the single crystal X-ray diffraction analysis is in agreement with that of IR measurement, both of them show that the Cu2+ is coordinated by two nitrogen and two oxygen. In addition, the thermostability and IR spectral of the compound were discussed.
